[I] [Bug] Partitioned topic deletion by topic GC [pulsar]
mukesh154 opened a new issue, #22471:
URL: https://github.com/apache/pulsar/issues/22471
### Search before asking
- [X] I searched in the [issues](https://github.com/apache/pulsar/issues) and found nothing similar.
### Read release policy
- [X] I understand that unsupported versions don't get bug fixes. I will attempt to reproduce the issue on a supported version of Pulsar client and Pulsar broker.
### Version
3.1.2
### Minimal reproduce step
- Fire up a Pulsar cluster with the "inactive delete" options enabled:
```
brokerDeleteInactiveTopicsEnabled=true
brokerDeleteInactiveTopicsFrequencySeconds=60
brokerDeleteInactiveTopicsMode=delete_when_no_subscriptions
brokerDeleteInactiveTopicsMaxInactiveDurationSeconds=600
subscriptionExpirationTimeMinutes=10
subscriptionExpiryCheckIntervalInMinutes=1
ttlDurationDefaultInSeconds=600
```
- Create a namespace with inactive topic policy deleted after 60 seconds. This is a default behaviour.
- Create a partitioned topic via pulsar-admin
- Produce a few messages to the partitioned topic. Do not create any subscription
- Check after a few minutes to make sure if the partitions are deleted or not and check the partitioned topic self still there or not.
### What did you expect to see?
The topic should be deleted along with the partitions because they weren't being used.
### What did you see instead?
The topic is never cleaned up only partitions are deleted. If you list the topics with the pulsar-admin tool the topic won't be listed, but when you try to create another topic with the same name it will say topic already exists.
### Anything else?
_No response_
### Are you willing to submit a PR?
- [ ] I'm willing to submit a PR!

May not be a bug. Check the broker.conf, this should be true but the default is false.
```
# Metadata of inactive partitioned topic will not be cleaned up automatically by default.
# Note: If `allowAutoTopicCreation` and this option are enabled at the same time,
# it may appear that a partitioned topic has just been deleted but is automatically created as a non-partitioned topic.
brokerDeleteInactivePartitionedTopicMetadataEnabled=false
```

It seems to be working with enabling the flag on `broker.conf`:
`brokerDeleteInactivePartitionedTopicMetadataEnabled=true`
The same flag is not there on `standalone.conf` and on adding manually, it is not working as expected.
So, it only works with docker & k8s deployments not on standalone.
Thanks @dao-jun @zzzming
